OPTICAL ANTI-COUNTERFEITING ELEMENT AND ANTI-COUNTERFEITING PRODUCT

摘要

Disclosed are an optical anti-counterfeiting element and an anti-counterfeiting product. The optical anti-counterfeiting element includes: a substrate (2), the substrate (2) including a first surface and a second surface opposite each other; a first micro-embossment structure at least partially covering the first surface, the first micro-embossment structure including a first micro-lens array (3) and a first micro-graph array (4); and a second micro-embossment structure at least partially covering the second surface, the second micro-embossment structure including a second micro-lens array (5) and a second micro-graph array (6); and wherein the first micro-lens array (3) is configured to sample and synthesize the second micro-graph array (6), so as to form a first reproduced image, and the second micro-lens array (5) is configured to sample and synthesize the first micro-graph array (4), so as to form a second reproduced image. According to the anti-counterfeiting element, a sampled and enlarged reproduced image may be observed from both sides of the substrate separately.
